SHAFT-HANGER.

SPECIFICATION forming part of Letters Patent No. 311,780, dated February 3, 1885.

Application filed June 16, IFF H. (No model.)

T 0 CLZZ whom it may concern.-

Be it known that I, WILLIs J. PERKINS, of Grand Rapids, in the county of Kent and State of Michigan, have invented a new and useful Improvement in Shaft-I-Ia11gers;andl do hereby declare that the following is a full, clear, and exact description of the same.

Hy invention is an improved hanger for shafting.

The object ofmyinvention is, first, to obtain a superior device for lining a journal-box, said box being adapted to the various positions in which journal-boxes are used; secondly, the object is to provide means whereby the journalboX may be readily adjusted in four directions without interfering with its stability or alignment; thirdly, the object is to so construct and arrange the various parts that all liability of breakage of the parts will be avoided; fourthly, the object is to provide improved means for holding the cap on, so constructed and arranged as to dispense with the ordinary devices used for this purpose, and at the same time to leave the box perfectly free for the reception of the shaft when the cap is removed.

My invention consists in the general construction,as shown, adapted to journal-boxes, and in the details, all as hereinafter explained, the principles of which are not only adapted to the general specific form shown of the complete hanger, but are also adapted to be used in other connections and in other forms of hangers. Ihave, however, hereinafter shown a convenient and substantial embodiment of my invention, the same being represented in the accompanying drawings, in which- Figure 1 represents a ceiling'hanger in end elevation. Fig. 2 represents the hanger as adapted to be mounted upon a wall or bridgetree box. Fig. 3 represents the hanger as adapted to be attached to a wall or post. Fig. 4 represents a section on line :0 ac of Fig. 1. Fig. 5 represents a central section of the san1e,taken on line y 3 of Fig. 2. Fig. 6 rep.- resents the modified form of the T-support in side elevation. Fig. 7 represents 1nodifications.

In these drawings, a is the cross-head, and b the supporting-spindle of the Tsupport for the journatbox. The spindle is mounted in bearings c c, of any suitable hanger, such as A of Fig. 1, or those shown in Figs. 2and 3, or

any other convenient form. The spindle is adapted to turn in these hearings, and it may be arranged on a vertical wall or post, as shown in Fig. 3, or beneath a horizontal ceiling or timber, as shown in Fig. 1, or above a horizontal wall, timber, or bridge-tree, as shown in Fig. 2. The hanger is provided with a set-screw and jam-nut, as shown at D, the screw bearing against the end of the spindle; or the end of the spindle may be screwthreaded and provided with a nut, as may be preferred, for obtaining vertical elevation. The cross-head a may be rounded or simi-cylindrical upon its upper face. The bearing E of the shaft is formed with a lower part or saddle, 6, with its under surface made to conform with the upper semi-cylindrical surface of the crosshead a, and the parts are titted to each other so that the saddle may be turned or rocked upon the cross-head, or may slide longitudinally. It is held against longitudinal movement by dogs ff, set adjustably in longitudinal slots in the ends of the crosshead,and held therein by nuts and bolts which jam the shoulders of the dogs against the upper surface of the cross-head. Lips upon the dogs f f project over the ends of the saddle and hold it closely when so placed, or the dogs f f may be made with an angle for contact with c. The bearing is formed of two parts, 1 and 2, of which the latter is integral with or rigidly secured to the saddle, and the upper part, 1, is properly fitted to the latter, and it is held in place by a yoke, F, the inwardly-turned ends of which bear upon lugs 3 3 upon the lower bearing. The set-screw 4., provided with the jam nut, is screwed through the upper or central part of the bail or yoke F, andprcsses against the cap or upper half of the box, holding it in place. The loosening of the set-screw is all that is neces sary tobe done in order that the yoke and the cap or upper part of the box may be adjusted in place or removed.

In the form shown in Fig. l the upper surface of the crosshead is below the bearingsurface of the shaft, but the bearing may be dropped by forming the surface of the crosshead as shown in Fig. 6, in which the central part is cut away, as shown at g, and the bearing with this saddle is modified accordingly, so as to let the part 2 down into the notch 9.

I do not limit myself to the exact form of T-support shown, as an inferior equivalent could be substituted, such as that shown in Fig. 7, where vertical lugs are used at its ends to form supports for pivotal screws, or a rod on or by which the box could be supported and horizontally adjusted.

The parts above described are adapted to the various forms of the supports shown, orv

to any convenient form of support, without change.

In Fig. 1 the hanger A is made with its upper part divided or separated, so as to admit the end of the cross-head (l, to have free play between the parts of the hanger.

In Fig. 2 the support or base A is adapted to rest upon a bridge-tree or any suitable horizontal support. In Fig. 8 is shown a bracket, A A adapted to be bolted to a wall or post. The bearings for the spindle are substantially the same in all cases, the supports for the bearing being varied according to the position for which they are intended.

From what has been said it will be understood that the, shalt-bearing has free motion, first, by the turning of the spindle in its bean ings; second, by the sliding of the spindle vertically in its bearings; third, by the rocking of the saddle on the cross-head. It may have a fourth adjusti'nent, not automatic, by the shifting of the dogsf, and it will be apparent, further, that anynne of these adjustments is independent of and in no way interferes with any or all of the others.

Having thus described my invention, what I claim is 1. In combination with a shaft, a journalbox mount-ed upon the crossbar ot' a T- support, said T-support being provided with suitable bearings, substantially as described.

'2. In combination with the shaft and journal-box, a T-support adapted to the journalboX, with its upper face rounded or semicylindrical in form, substantially as described.

3. A journal-box for shafting, having its -adapted thereto, and means, substantially as described, for insuring its horizontal adjustment on the cross-head.

6. The combination, with ajournalbox for shafting, composed of two separate parts, of a bail detachably secured to one part and encircling the other, and a set-screw where by the two parts of the box are held together, substantially as described.

7. A'journal-box for shafting, having a lower part or saddle formed with a concave face, in combination with the cross-head, formed with a "convex face, adapted thereto, the parts being fitted to each other, substantially as described, whereby the journalbox may have rocking or longitudinal movement upon the cross-head.

8. In combination with thejournal-box for shafting, having a saddle and T support, with a semi-cylindricalsurface upon its cross-head, adapted to the saddle and permitting rocking or longitudinal movement, a spindle, b,

adapted to turn or move vertically in its bearings, all substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
